F-1208 C-4011 COIL WINDING METHOD FOR MAXIMUM UTILIZATION OF WINDING ENVELOPE Abstract of the Disclosure A coil winding method wherein only one-half turn is wound in the bottom slot of the first layer of the coil. This results in the loss of one-half turn, but causes the normal crossover from the first layer to the second layer to occur on the side of the coil opposite the lead-end. The last one-half turn of the second layer wound in the bottom slot of the first layer, thereby recovering the lost one-half turn. Additional turns are added in this manner until approximately one-half of the layers have been wound. Thereafter, the usual progressive winding method is employed. As a result, crossover related build-up in the completed coil is distributed between opposite sides of the coil and the number of turns within the allowable profile is substantially maximized.
